Application August 20, 1943, S e rial No. A4,991,361

This inventiony relates to receptacles used for the preparation of coffee and particularly such receptacles as commonly referred to as the Silex type of coffee pot. More particularly, the invention relates to'an attachment for use in connection with the upper or brewing vessel of coffee preparing devices of the kind mentioned forming a cover for said vessel, a holder or support for the vessel when inv inverted position, as well as a receptacle for receiving the grounds when the vessel is in inverted position. Still further, the attachment provides a means for simplifying the operation of cleaning the vessel in removing the grounds therefrom' and in nally disposing of the grounds.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters infeach of the views, and in which:

Fig. lis a diagrammatic view showing a coffee pot of the type and kind under consideration in normal brewing position in full lines and with the brewing vessel removed and in inverted position in dot and dash lines in illustrating the use of my attachment.

Fig. 2 is an enlarged sectional view through the attachment illustrating the same mounted on the open end of the Vessel.

Fig. 3 is a section on the line 3-3 of Fig. 2; and

Fig. 4 is a section on the line 4-4 of Fig. 2.

In Fig. 4l of the drawing, I have illustrated at I6 the bottom part of a coffee pot or device of the general type and kind, commonly referred t as a lSilex 'I'his bottom portion includes a handle member II facilitating the vdischarge of the coffee, when prepared, from the pot I0 and after the upper brewing part or vessel I2 has been removed, as is indicated in dot and dash lines in said figure. The vessel I2 includes at its nec-k portion `a handle member I3 facilitating attachmentfand detachment thereof, as well as other handling of the vessel, and projecting from the neck is the conventional spout or tube I4, which extends into the vessel I0. The vother details of construction of the device are not dealt with, as they form no particular part of the invention and it is commonly known that in apparatus of this kind, strainer devices are arranged in the neck portion I of the part I2, which retain the coffee grounds at all times within the vessel I2.

7 claims. (c1. sig-232) The attachment comprises a substantially cupshaped casing I'I, the bottom wall of which has a large opening I8, which is further enlarged by notches I9 arranged on opposed walls thereof, as will clearly appear in Fig. .4 .of the drawing. The upper end of the casing I' has an outwardly and upwardly extending ange portion 2li, which .et 'fit1-have illustrated .011e of my attahmeiiis 55 forms an annular recess 2 I, in which is preferably arranged a packing-ring or gasket 22.

Opposed Walls .of the casing Il, near the flanged end 20 thereof, have recesses 23 for the reception of 'springs 42li, having projecting, lcurved or rounded ends 25, which are adapted to enter the opening 26 in the top of the receptacle I`2 and to rmly engage the walls of the receptacle in supporting the attachment I6 thereon. The springplates 24 are retained against displacement by rivets or other fastenings, as indicated at 21. However, the contour of the plates will conform with the ,recesses or sockets 23, this' keying the plates' against any shifting movement on the container Il'. f

Y A cap 28 is Vdetachably Vcoupled with the casing I1 and this cap comprises a saucer-like body hav-r ing an upwardly extendingperipheral flange y29, which Vforms a shallow receptacle 30 to catch any drainage from the coffee grounds, when the device is in the inverted position, as `is shown in dot and dash lines in Fig. 1. The Ycentral portion of the cap 28 is domed, as seen at 3|, which provides a recess 32 in the bottom of the cap. Transversing -this recess is a bar 33, which forms a finger-piece facilitating attachment v and rdetachment of the cap. On the top of the dome is a corresponding bar or rib 34, which terminates in bevelled end walls 35, note Fig. 3, and these walls engage the bottom of the container VI 1, in retaining the cap againstv displacement from the container. It is understood, however, .that the greatest width of the rib is such as to freely pass through the notches I9, in attaching and detaching the cap. `When the cap is attached, the bar 34 is moved into a position at right angles to the notches I9, as is clearly illustrated in Fig. 4 9i the drawing- The central portion 0f the dome il is offset, as seen at 3 6, and on the periphery 0f this offset is V formed circumferentially spaced ribs or knurlf ings Si, which are diseased ai the periphery of the opening I8 in the bottom of the container Il, so as to form adrainage from the container. 11n other words, thefcap "2.8 forms what might. be termed a strainer, .Which `will allow the passage of fluid through the ,bottom 0f the Container. hilt will retard or retain thesriinds within theconiairieii,

grounds have been placed in the receptacle andthe required iluid arranged in the lower receptacle Y II), preparatory'to making coffee. By reason of the packing 22, itrwill be apparent that in the Vpreparation of the greatest capacity or number of cups of the apparatus, in the event of a bubbling over or excessive agitation of the brewingin the vessel I2, the attachment will forma supple# mental extension chamber, in which this excessive bubbling or brewing can take place with-g out any loss of the fluid. While this Vexcessive bubbling should not be permitted, often times, by

oversight, it occurs and as a result, a loss of the fluid is experienced. It will be understood that the cap provides the necessary ventilationthrough the passages 38 to properly vent the top vessel I 2.

After the brewing is over and the coffee has,

been transmitted from the vessel I2 into the vessel I0 and nothing but grounds remain in the vessel I2, this vessel is then, as usual, removed from the vessel I0 and, vby reason 0f the attachment I6, can be placed in the inverted position, illustrated in dot and dash lines in Fig. 1 of the drawing with the cap 28 resting on a suitable support. In this position, most of the grounds are permitted to fall and collect in the casing I1. Some fluid, which may still prevail in the grounds, can drain off and be collected in the receptacle 39 of the cap and thus prevent it from passing onto the surface of the support on which the inverted receptacle is arranged. 1

When it comes time for cleaning thereceptacle I2, if some'of the grounds still'remain adjacent the neck of thereceptacle, the entire unit, as appearing 1in -dot and dashlines in Fig. 1, may be placed under a faucet allowing the water to pass through the tube I4 into the receptacle I2 to thoroughly flush out and clean out lthis receptacle in removing the grounds. Thereafter, the attachment I6 is removed from the receptacle I2 and the groundsmay. then be conveniently disposed of and this operation Vperformed without any destruction orinjury to the receptaclevIZ,V

which is usually composed ofglass. In this con'- nection, it will be understood that the attachment I6 in its entirety and with the possible exception of the spring clips and packing 22 will be com,- porsed of plastic material. n v

The cap 28 may readily be detached from the casing I'Iv in cleaningout the attachment preparatory for the next use and all parts are freelyY further', in dispensing of the coffee grounds andV to avoid the more orV less conventional practice Yof allowing'V the grounds to pass through the 'drainpipes of a sink, the arrangementV of the grounds in the receptacle facilitates disposal of the grounds in a garbage can orother means of 1 the coffee grounds, a means for draining the coffee grounds'in eliminating more of the moisture therefrom and a base for supporting the brewing part in inverted position.
